Photodynamic therapy: application in cosmetology
A biochemical approach to the problem of aging
With age, a person accumulates various "damages" in the cells and intercellular space, which were not detected in time and corrected by the body's restorative systems. Glycation, oxidative stress, limited number of fibroblast divisions (Hayflick's limit), accumulation of senescent cells, genetic polymorphisms and much more negatively affect not only the quality of the skin, but also the body as a whole
Aging should be considered as a systemic pollution of the body.
Our task is to clean tissues at the molecular-cellular level from cells with altered metabolism and damaged cells, which will allow us to preserve their health and, therefore, their youth. And photodynamic therapy (PDT) will help us in this.
Today, PDT is successfully used not only in oncology, but also in many other fields of medicine, including dermato-oncology and dermatology: treatment of basal cell cancer, various skin keratoses, psoriasis, lichen sclerosus and many other diseases. In cosmetology, PDT is successfully used in the correction of involutional skin changes, the treatment of acne, rosacea, the preparation and rehabilitation of tissues before and after plastic surgery, and the treatment of scars.
Features of the method
PDT is based on a combination of preferential accumulation of photosensitizer in pathologically changed cells and their subsequent death when interacting with light. In the place of destroyed cells, new, healthy ones appear. At the same time, metabolic processes in the cells are activated, the level of immune protection of the body in general increases.
